Sika® CarboDur® S

Pultruded carbon fibre plates for structural strengthening as part of the Sika® CarboDur® system

Sika® CarboDur® S plates are pultruded carbon fibre reinforced polymer (CFRP) laminates, designed for strengthening concrete, timber, masonry, steel and fibre reinforced polymer structures. The plates are bonded onto the structure as externally bonded reinforcement using Sikadur®-30 epoxy resin based adhesive for normal temperatures, or Sikadur®-30 LP epoxy resin based adhesive for elevated temperatures during application or service. Please refer to the relevant Product Data Sheet for more detailed information about each of these adhesives.

Usage

Sika® CarboDur® S is used as a reinforcement plate for externally bonded structural strengthening systems on concrete, masonry, wood, steel and reinforced polymer substrates. Externally bonded structural strengthening systems are used for:
  • Enhancing the load-carrying capacity or ductility of structural members
  • Increasing the flexural loading capacity of elements and structures
  • Improving fatigue resistance
  • Reducing the stress on steel reinforcement
  • Structural upgrading of weak concrete elements or structures
  • Replacing missing steel reinforcement
  • Changing the structural system (removal of floor or wall sections)
  • Repairing structural elements after damage (vehicle impact, fire, earthquake)
  • Improving impact resistance
  • Passive strengthening for seismic event protection
  Please note:
  • A specialist structural engineer must be consulted for any structural strengthening design calculation.
  • The Product may only be used by experienced professionals.

Application steps

SUBSTRATE QUALITY

SIKA® CARBODUR® PLATES EXTERNALLY BONDED TO THE CONCRETE SURFACE

Recommended minimum concrete pull-off strength after surface preparation:

  • Mean: 2.0 N/mm2

  • Minimum: 1.5 N/mm2

The effective concrete pull-off strength after surface preparation has to be verified. If concrete pull-off strength is below the stated minimum requirements, alternative Sika solutions are available:

  • Sika® CarboDur® applied in slots as near surface mounted (NSM) reinforcement

  • SikaWrap® fabrics: Please refer to the Product Data Sheet for the SikaWrap® fabrics

Concrete must generally be older than 28 days (dependent on curing conditions and the type of concrete).

SIKA® CARBODUR® EXTERNALLY BONDED TO OTHER SUBSTRATES

For the application of Sika® CarboDur® plates to all other substrates (brick, stone, steel, wood, fibre reinforced polymer) please refer to Ref: Sika Method Statement 850 41 05 Sika® CarboDur® System. Contact Sika Technical Service for detailed advice.

SUBSTRATE PREPARATION

Clean and prepare the concrete to achieve a laitance-free, contaminant-free, open-textured surface.

Refer to Ref: Sika Method Statement 850 41 05 Sika® CarboDur® System for further information.
